rack accommodating a large number of rolls and presenting theends of theroll boxes in positionto facilitate the reading of their titles. Afurther object of'my invention is to: provide a knock-down rack of suchcon-' struction-that its shelves may be collapsed on the frame and thebase detached and confined within the frame,; so that when not in usethe rack parts may be brought intlg a a structure withjparts of suchcharacter that they can be cheaply fabricated and standardized, thusinsuring low cost of manufacture.

In the accompanying drawings,

Figure 1 is a vertical elevation of a rack in which my invention isembodied in one form;

Fig. 2 is a perspective of one of the rack shelves and portion of theconnecting bars;

Fig. 3 is a horizontal section through the rack;

Fig. 4: is a side elevation of the rack collapsed; and

Fig. 5 is a vertical section through the rack in opened position.

The construction here illustrated comprises a base 10 having on'itsupper face a central boss 11 and tapped hole 12 into which takes thescrew stem 13 of a wooden pivot pin 14, provided with a knob 15 tofacilitate its insertion. Upon the cylindrical body portion of the screwand beneath the retaining flange 16, is swiveled the bottom bar 17 of anopen frame, oblong in plan, the side uprights 18 and 19 of which areunited at their upper ends by a cross bar 20 of any suitable type, hereshown cylindrical and secured to the uprights by screws 21. Between theuprights 18 and 19 are pivoted, at their inner ends, two series ofsuperposed shelves 22, 23, 24, 25, 26, 27,

one series on each side of the mid-plane of Specification of LettersPatent.

of each series are pivoted toconnecting bars 28 and 29, one on each sideofthe series and serving to maintain the shelves in pres determinedspaced relation. At their upper ends the bars 28 and 29, are jointed tolinks 30-and 3,1 which have-at their inner ends bayonet slot openings 32adapted to take. over; pins 33 and '34 on the inner face of the uprights18 and 19 and so located that when,

' the uprights. At their'outer ends the shelves the pins lie at, the endof the bayonet slots the links .holdfthejshelves' in such inclined,

position that the titles on the ends of the music rollboxes arepresented at an angle which facilitates. their reading.

'Each'shelf hasside and bottom flanges 36 which serve to retain themusic roll boxes on theshelves. The connecting bars28 and 29 arepreferablyvof channel section, the ends of the outwardlyiextended ends37' ofthe side flanges 36 lyingwithin the channel 38 and being thusconcealed by the bars28 and 29. The channel 38 ispreferably locatedtoone side of the center of the bar so that the thin wall 39 faces theshelf and limits as littlev as possible the available a space for themusic roll boxes.

It will be noted that the inclination of the shelves is such. that thecenter of gravity-of the rolls supported thereby falls within the areaof the base 10. Consequently even were the rack loaded only on one sidethere would be no danger of tipping it over.

If the rack is to be stored or shipped the links 30 and 31 aredisengaged from the pins 33-34 and the shelves folded upward so thatthey lie between the side uprights 18 and 19 of the frame and are thusprotected during shipment. In this position the sidebars 28 and 29 lieagainst the edges of the uprights. It will be noted that the outer endsof the side flanges 36 are cut away to permit this. The pivot pin 15 mayalso be unscrewed and the detached base 10 may be placed between theshelves and the uprights of the frame, where it may be secured in anyconvenient way during shipment or storage. It will be noted that theuprights 18 and 19 and their end pieces 17 and 20 form a protectiveframe surrounding the shelves so that the crating 0r boxing of the rackis a very simple matter.

The ordinary construction of the present rack comprises six shelves,each accommodating six roll boxes of ordinary size so that.

rolls on each side or seventy-two rolls in all. If large boxes areplaced upon the two lower shelves on each side, five may be accommodatedon each shelf, and'the total capacity of the rack is thus lowered tosixty-eight, including thetwenty boxes-of large size. It will also benoted that the lower two shelves 22, 23, are spaced a Slightly'greaterdistance apart than the upper shelves to accommodate the boxes of largersize.

The construction illustrated is adapted for either wo0d or sheet'metalfabrication, and I do=not limit myself to either material. Therac'lec'an be made in large quantities at much lower cost than" anordinary music roll cabinet,- oc'cupies little or no more roomin spiteof its greater capacity, and presents many obvious practical advantagesthereover, 1n

additionto that of economy. Various modificatlons in detail ofconstruction will readily occur tothose skilled in'*th'e art which donot depart from what I claim as myinvention.

Thus for instance, chains may be used instead of the solid links 30'anda plain angle bar maybe substituted for the'chann'el bar 28.

I claim:

1. A-raclrfor player piano roll boxes comprising a fioorbas'e, arectangular frame iaving bottom, top,- and side members rigidlysecured*together, a-sw-iveling connection between said bottom member ofthe frame and the base, together with two series of up wardly' inclinedshelves extendingflbetween Copies ofltmspatent' may'be obtainedfor fivecents eachyby addressing-the Commissioner of Yaten'ts,

on one shelf extend above the lower margin of the shelf next aboveandthe upper ends of the roll boxes on all the shelves are presented atan angle to facilitate the reading of their titles, the inner marginsofthe shelves of the opposed series being spaced apart to leave acentral open area intowhich the innermost corners of the rollboxes-project,

and means at the inner margin of each-shelffor supporting the lowerinner corner of the rollboxes placed thereon, the shelves of each seriesbeingpivoted tosaid side members of the frame and folding upward againsteach other into a substantially vertical position, the pivots ofadjacentshelves being spaced apart a less distance than the width of'theshelves.

2; In a construction such as specified in claim 1, means for collapsingthe shelves substantially into the plane of the side uprightsfor storageand shipping purposes.

In testimony whereof Ihave signed my name to'tlns specificatlon.
